Could ethanol vapor collect in low spots?

Chemistry
1 answer:
Leviafan [203]3 years ago
6 0

Answer:

Yes

Explanation:

Denatured ethanol fuel is a polar solvent, which is soluble in water. A

Polar solvent is a compound with a charge separation in chemical bonds, such as  alcohol, most acids, or ammonia. These have affinity with water and  will dissolve easily. Denatured fuel ethanol has a flash point of  -5 ° F and a vapor density of 1.5, indicating that it is heavier than air.

Consequently, ethanol vapors do not rise, similar to the gasoline vapors they are looking for  lower altitudes. The specific gravity of denatured fuel ethanol is 0.79, which  indicates that it is lighter than water and has a self-ignition temperature of 709 ° F and a  boiling point of 165-175 ° F. Like gasoline, the most denatured fuel,  the greatest danger of ethanol as an engine fuel component is its flammability.

It has a wider flammable range than gasoline (LEL is 3% and UEL is 19%).

asambeis [7]

Answer:

Photosynthesis

Explanation:

Photosynthesis can be defined as the process whereby plants, some protistans, and some bacteria utilize the energy from sunlight to produce glucose from water and carbon dioxide. In early spring, there is the shift of plants from scanty winter branches to abundant spring leaves. When the leaves on the trees reduced in the fall, dead plants break down throughout the winter due to the activities of microbes. The microbes decompose the plant materials and generate carbon dioxide. This leads to increase in the level of carbon dioxide in the atmosphere. In the spring, leaves return to the plants/trees and the rate of photosynthesis increases greatly. This consumes more carbon dioxide and the level of carbon dioxide in the atmosphere reduced.

Calculate the vapor pressure at 25 ?c of hexane above the solution. the vapor pressure of pure hexane at 25 ?c is 151 torr.
Studentka2010 [4]
One of the many ways in order to solve for the vapor pressure of pure components at a given temperature is through the Antoine's equation which is written below,
                                    P = 10^(A - B/C+T)
where A, B, and C are constants and T is the temperature in °C and P is the vapor pressure in mm Hg. 
For hexane,
                             A = 7.01
                             B = 1246.33
                             C = 232.988

Substituting the known values,
                            P = 10^(7.01 - 1246.33/232.988+25)
                             <em> P = 151.199 mm Hg</em>

A plate moves 200 m in 10,000 years. What is its rate in cm/year?
Varvara68 [4.7K]

Answer:

The answer is

<h2>2 cm/year</h2>

Explanation:

To find the rate in cm/year we must first convert 200 m into cm

1 m = 100 cm

if 1 m = 100 cm

Then 200 m = 200 × 100 = 20 ,000 cm

So the rate is

<h2>\frac{20000}{10000}</h2>

<u>Reduce the fraction with 10,000</u>

We have the final answer as

<h3>2 cm/year</h3>

Hope this helps you

Which of the following is an aldehyde?
balu736 [363]

Answer:  CH_3CH_2CH_2CHO has aldehyde functional group.

Explanation:

Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

A.  CH_3CH_2CH_2COCH_3 has ketone C=O functional group .

B.  CH_3CH_2CH_2COOH has carboxylic acid COOH functional group .

C.  CH_3CH_2CH_2CHO has  aldehyde H-C=O functional group .

D. CH_3CH_2CH_2COOCH_3 has ester RO-C=O functional group .

Thus CH_3CH_2CH_2CHO has aldehyde (CHO) group.
